To all whom t may concern: Be it known that I, SAMUEL B. BYNUM, a citizen of the United States, residingl at Jackson, in the county of Madison and State of Tennessee, have invented certain new and useful Improvements in Spring-Motors, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to improvements in controlling devices for motors particularly spring motors, and it consists oil the novel construction and combination of parts heroinaft-er described andclaiined.

lThe object of the invention is to provide a regulating or controlling device of this char -t aeter which will be simple and pi'ai'tical iii through a casing of' a spring motor showing construction and Convenient to operato, and by means of which the motor may lic instantly stopped or started and made to run at any desired speed.

The above and other objects are attained in the preferred einliodiinent of the inven'n tion illustrated in the drawings, in which Figure 1l is a detailed vertical section v my improved controlling` or governing decarry centrifugal weights 11.

vice applied to the latter and F ig. 2 is a detailed ers ective of a portion of the device.

In tile rawings 1 denotes a portion` of a casing oreovering of a spring motor 2 having a frame 3 and a main drive shaft l, On the latter is Vfixed a'beveled.4 gear 5 which incslies with a beveled pinion 6 iixed upon the lower end of'a sleeve 7 arranged for sliding inove- .ment on the governor shaft This shaft has its upper end mounted in a suitable bearing upon the easing 1 and its lower end mounted' in a bearing upon the frame 3. The sliding sleeve 7 is connected t'o a stationary collar 9 adjiistably fixed upon the upper portion of the shaft 8, by lsprings 10 which These vweights ily outwardly when the governor isrotated and boW the springs 10 so that the sleeve 7 is drawn lupwardly on the shaft and the pinion 6 is thereby lifted out of mesh, with the gear 5 which rotates it. The sliding sleeve 7 also carries a brakedisk 12 arranged immediately above the pinion and adapted to eo-act with two levers 18, 145 arranged nponthe frame 3.

The lever 14 is ada ted to engage; the upper face of said disk while the lever 13 is adapted to engage the lower face of the same and comprises a body of rightangular form. pivoted intermediate itsl ends upon a bracket 15' and having one of its ends 16 projecting upwardly' to provide a handle 'and its end i7 projecting inwardly so that it may beswiing up under the disk- 12 -to en age and elevate the latter and thereby lift tlg v 6 out oil' inesh with thegear 5. The lever is thus operated when itis desired to speed the niotor since the ngovernor thereby thrown out of operatioifand the iiiotor is allowed toA riin lree. The lever 13 may also be used as a brake for instantly stopping the motor; by 'lirst adjusting the lever 141, as presently eX- plained, 'so that the disk 12 cannot be raised a distance siillicient to iiiovo the pinion 6 out olx iiiosli with the gear 5 and then operatiner lever 1b so that its end 17 presses the dish against the lever 11,

.llie lever 14 is pivoted intermediate its ends to a vpost 1S iipon the l'raine 3 and has its' inner end ell'sct and apertiired to receive a friction headv or stud 15) adapted to bear against the upper surface ol the brake disk 12. ilie opposite end 2O olt the lever'M is adapted to lio ei'igagcd and forced. upwardly by an :id iiistii'ig screw 2l airai'iged in the `l'raiiie and having at its lower end a milled head between which and the frame is pi'o-A vided a tension spring 22. Vvvheii the screw 21 isinoved upwardly the lriction head 19 ol' the brake lever is forced downwardly upon the brake dish 12 to check the rotation of the latter and hence the speed of the motor.,`

26 atitsotlier. This tongue 26 is adapte to engage and slide upon the straight upper edge :Z7 of the lever 14 and to swing over the' pivot or liilcrnln oli the latter., Said ton ile isrsiilliciently resilient to force either en of the lever 14 downwardly when itis-moved upon either side ol the pivot or liilcruin/post 1S. Then the tongue 25 is moved out'- wai-diy toward end .QO oi". the lever 14' the,

i friction head. 1Q is elevated. from the brake disk, and when moved inwardly lsaid head 19 is forced (.loi'vnwardly to theek the rotation of the governor. Having thus described my invention what lolaimis: 1. In a spring motor, tlieeoinbination with a shaft, of a governor shaft, a brake disk slidable on thelatter, a gear carried bysaid disk,

a handle 25 at one end anda resilient ton ne v ioo 'e gear on the inotor shaft to lnesn 'v i to the governor Shttend it the other end to Said brake disk, Weights upon seid springs` and Ineensy for elevating the brake disk to throw .its gear out' of mesh with the geel' on the motor shaft.

2. In a spring motor, the combination with a shaft, efe govern sh aft, a, Drake disk slidable on the letter, a gear carried by seid disk, a gear on the inotor'shat't to mesh ,with the first. mentioned one,l springs fixed et one end to the governor Shaft and at the other end to .said brake disk, Weights noon said springs, and e lever forelevatng tliie brakedisk to throw its gearout O mesh with the gear or the motor shaft.

3,. n e, spring motor, the Combination with a shaft, of'e governor shaft, e brake disk siideteleon the latter7 e gear carried by said disk, a gear on the motor shaft to mesh with the first mentioned one, springs fixed at one end to tiyiegovernor shaft and at the other end to said brake' disk, Weights upon sind sprinfe, e

'ineke lever to eo-rivet with 'the' brake dink7 momie ,forndjueting Said brake lover :md :Lnotiier lever for engagement with the oppoeito Side oi the brake disk for the purpose epevi lied. v

'n a? motor5 the combination with :1. shaft, of e governor shaft :L geur slidubly urrnnged upon the governor Shaft, n centrifugnliy acting device between sind. gem' :ind Said governor shaft; n, gear upon the motor shaft adapted to be engaged by the gem: on the governor shaft and :i` lever pivoiml intermediate its ends and having one end formingl n.. imndie and its other end adapted to lift 'the gear on the (rovelnog shaft out ofwmosh with the gen/r on the inotrn shaft, surbstaui'inily :is d eseri bed.
